Proxmox HA with two hosts

[joblack]

Hi,

I was testing Proxmox 6.x with two hosts and HA. It worked so far but I cannot upgrade to Proxmox 7 because it says I need more hosts.

Is Proxmox 7 still working with two hosts and HA?

HA in general atleast needs 3 hosts for quorum. If you just want 2 servers you could get a cheap raspberry pi and use it as a qdevice for the third voter:

Thanks I will look into it. I am wondering why it worked before with 2 hosts and Proxmox?

Did you really tried to take one host offline? If you do the other host should stop working too to prevent screwing up data when quorum is lost.
